Product Code : SC-AF02
It is one kind of specially Brown Fused Alumina grain for abrasives application. Brown fused alumina is fused in a special ace furnnace,named tilting furnace.The Lump made from this kind of furnace have the very small crystal than Fixed Furnace, so the products have the higher toughness and better anti-impact ability, It is well used in vitrified application and can improve the grinding efficiency.

The grains of this type of Brown Fused Alumina are re-heated at 800℃-1,200℃ and the purpose is to renovate the crack on the surface and interior of crystal and then to improve the toughness and anti-impact ability of grain. After re-treated, the product can increase the using time of the bonded abrasives products. The appearance of the grain is low blue colour.
